Fair enough
Though most content during leveling, outside of reaper and with all the possibilities of self healing, items and buffs, it probably got so easy that throwing a heal on any character most likely overheal by a huge margin. In fact most groups I see that play outside of reaper don't have a healer at all. Independent of that, a budy of mine nearly exclusively played healers for several years and he didn't eventually left because of PMs not being able to get healed. But as far as I know him, he probably would now leave when they get it. So forgive me, but I somehow doubt they all left because of the difficulties with PMs.
And yes, throwing a heal or cure on any character and not seeing the HP bar move is frustrating. And I get and understand it, why a healer like a nice QoL change, especially for reaper, even thou everyone keep saying that the game is not designed around reaper.
Anyway, the devs made it essentially clear that no matter the arguments against, they already made up their mind and this change is here to stay. So I will just shrug and go on...
